PIN.

Specification of Letters Patent.

Patented June 16, 1914.

Application filed August 19, 1912. Serial No. 715,866.

To all whom it may concern Be it known that I, JUAN B. RAMIREZ, acitizen of the United States, residing at- VVarren Point, in the countyof Bergen and State of New Jersey, have invented certain new and usefulImprovements in Pins; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to pin fasteners, and more especially to thoseadapted for connecting sheets of paper, although the pin is not at allso limited in its use and, in fact, in some essential particulars itmight be designed for the purpose of connecting other articles thansheets of paper.

The objects of the invention are, first, to reduce the likelihood. ofsticking the fingers or engaging the pin point with other objects whileit is in place; second, to shape the pin in such manner that the sheetsof paper will lie as flat as possible while connected; and third, toprovide means whereby the pin will be held against accidentaldisplacement, although yet permitting it to be manually withdrawn at anytime. These and other objects are accomplished by making the shank ofthe pin straight throughout most of its length and deflecting itsextremities in opposite directions to a slight degree and on curvedlines rather than angularly. In the following specification and claimswill be found the details of construction of several embodiments of thisidea, as shown in the accompanying drawings wherein Figure 1 is a sideelevation of the simplest form of this pin, having an ordinary head, thesame conforming nearly to the construction of the ordinary toilet pinnow in every day use. Fig. 2 is a front elevation and a. side elevationof a pin whose shank is formed in the same manner but whose head isflattened and herein shown as formed into an eye. Fig. 3 is a'frontelevation and a side elevation of a similar pin whose flattened head isformed into the shape of a loop bent back over the shank of the pin.Figs. 4, 5 and 6 are diagrammatic views showing the manner of insertingthe pin through a flat piece of paper. Figs. 7 and 8 are similardiagrammatic views showing how the pins of Figs. 2 and 3 could beinserted through a piece of paper.

In all views of the drawings, the numeral 1 designates the shank of thepin which is preferably perfectly straight, being made of round, finewire, as usual, and of the de sired gage and length and finish; and inFig. 1 I have shown at 2 how this shank may be roughened as by theformation of notches therein, if desired. The lower end of the shank iscontinued into what we will call a rearward bend 8, beyond which is thetip 4 having a pointed extremity 5, and the length of the tip isunimportant as is also the exact degree of its deflection out of theaxial line of the shank 1. By the dotted lines in Fig. 1 it will be seenthat such deflection is something less than 45. This detail is notmaterial, although it is to be noted that the bend 3 is a gentle curveand there is a distinct absence of any pronounced angle at this point.The outer or upper end of the shank is bent in an opposite or What wemight call a forward direction at the point 6, beyond which it iscontinued ina neck 7 whose length is preferably about that of the tip 4:and Whose angularity is probably about the same so that these twoport-ions of the pin stand in parallel lines, as the dotted lines willshow in Fig.7 2. The bend 6 again avoids angles, and is struck on agentle curve as shown, and for purposes which will appear hereinafter.

The head of this pin may be variously formed. In Fig. 1 it is a smallbutton or flattened disk 8 standing in a plane out of the axis of theshank and at right angles to the length of the neck 7 which is rigidlyattached to its center; in Fig. 2 the head 9 is formed in the shape ofan eye or a small ring, but in this case it stands slightly oblique tothe line of the neck 7 and in a plane parallel with the axis of theshank l; and in Fig. 3 the head 10 is formed in the shape of a loop orring of considerable size, but instead of upstanding from the neck 7, ithangs pendant from the same although it is rigidly connected therewithat the'point l1, and here again the plane of the head 10 is parallelwith that of the shank 1. These illustrations will be suflicient toemphasize the fact that the gist of the present invention lies in theshape of the shank and the neck and tip thereof, and the shape anddisposition of the head of the pin will depend upon its use. It is quitepossible that a large or fancy head could be formed on or attached tothe same, or the pin could become a part of some other device withoutdeparting from the principle of the invention. As to the head, I wouldsay that I prefer that it shall be flat and shall stand out of a planewhich would extend through the axis of the shank 1.or neck 7.

Figs. 4, 5 and 6 illustrate the manner in which a pin of this characteris inserted through a sheet of paper, and for sake of simplicityandclearness I have illustrated but a single sheet although in use thepin will doubtless connect two or more superimposed sheets. Fig. 1 showsthe first step after the pointed extremity 5 has been passed through thepaper sheet P and the tip 4: pushed through the hole 12 in the directionof the arrow 12, so that the bend 3 will lie within the hole in thepaper. To insert the .pininthis manner, the operator who would beat thepoint 13, would first turn thepin so that its tip 4 would be toward himand its head 8 away from him, pass the point 5 downward through thepaper and move the tip in the direction of the arrow 12, and then turnthe entire pin downward in the direction o-f2the arrow 14:. Fig. 5 showsthe next step where the straight shank 1 has been slipped through thehole in the paper andthe tip a is about to be passed upward in thedirection of the arrow 15, and the operator accomplishes this step withmy improved pin in precisely the same manner thatlhewoulduse an ordinarypin, but with I the advantage that the upturned tip 4 is in position topenetrate the paper P for the secondwtime with extreme case, and no bendwhatever has yet'been made'in the sheet of paper. Fig. .6 illustratesthe third step, or

rather the position of parts after the 13111511516 been put into place.zVVhen the tip has passed through the paper the second time, as it isabout to do in Fig. 5, continued movement in thedirectio-n of the arrow16 causes the entire pin to rotate on its axis automatically for aone-half revolution, by reason of the fact that the deflected neck 7 asIItIPFISSBS through the first perforation 12 in the .paper brings outthis automatic rotation as :a result of pressure in the direction 16.n'llhe rotation occurs while the pin is passing through the secondperforation 17 in the paper and continues until it comes to rest asshown in Fig. 6; the result is that the paper is forcibly bent upwardslightly at the point 18 so that the lower end of the shank 1 maypassthrough the second perforation 17 inanoblique direction, as shown.Butthe advantage resulting is that the rearward bend 3 finally comes torest just below said second perforation 17 and the point 5 .of the pinis turned downward toward the paper and caused to rest-thereon. Theresult-is-that the operator will not be likely to prick his fingers onthe point nor catch or .tear other pieces of paper thereon. It shoulddiffers from others of which portant members herein called the the neckbe noted also that the paper is bent upward but once and to an extremelyslight degree, and the flattened head (whatever its form) lies closeupon or against the fiat portion of the paper next to the perforation12, and avoids the well known hump which is found in all commercialpapers that are connected by the ordinary pin now in daily use, andwhose head stands at that time on edge or in. a plane at right angles tothe axis of its shaft rather than in a plane oblique thereto as shown inFig. 6 or parallel therewith as shown in Figs. 7 and 8. Any form offlattened head used in connection with my improved pin facilitates therotation above referred to or at least permits it. and if the head heamplified as shown in Figs. 2, 3, 7 and 8, the fact that it is largerand flattened gives it a larger bearing surface on the paper to preventthe pin shank from turning over so that the point would stand upward.

In removing the pin from its position illus trated in Figs. (3, 7 and 8,it is only necessary to grasp-the head and draw upward or toward thenumeral 19 which would be away from the operator, meanwhile giving thehead a. partial rotation after the neck 7 has passed out of theperforations 12. At this vious that, while it could be passed throughone or more sheets of-paper as shown in the drawings without creating anundesirable hump thereln, it could be used to equal advantage on fabricswhether the same were flexible or highly starched, and in its insertionand withdrawal it would not make an unsightly hole or causethe materialto be crimped or bent to a great degree.

It Wlll be unnecessary for the purposes of this specification to go intothe manner of .makingthe 3111, or give any details as to its size,materia and unimportant details.

I am aware that hitherto efforts have been made to defiectthe shaft orshank of a pin out of a true straight line :for the purpose of causingit to remain in place securely, or

causing it to worm or screw itself into place as it is inserted. But, myimproved pin I am aware to the extent that its shank so-called isperfectly straight throughout its entire length and is deflected ongentle curves and without any angles into relatively short and unimtipand which stand oblique to the axis of theshank and on oppositesidesthereof.

I consider the use of a downturned tip 4 of advantage in holding thepoint 5 against the paper P, only when the neck 7 is upturned in theopposite direction so that when in place this neck will hold the tipwith its point 5 against the paper rather than permitting it to turnover and project up- Ward; and, of course, the use of a flattened headbut more firmly prevents the rotation of the pin after it has been putin place.

My improved head avoids undue bending of the material P by having thedeflected neck 7 adjacent the head of the pin, and in no case will Idispose said head in a plane at right angles to the axis of the shank,or in the plane thereof.

hat is claimed as new is 1. The herein described pin comprising arelatively long straight shank, bent aside at one end and continued intoa relatively short straight tip standing oblique to the axis of theshank and having a pointed extremity, the other end of the shank beingbent aside in the opposite direction into a relatively short neck, and aflattened head at the outer end of said neck standing wholly out of theline of the shank and in a plane transverse to the common plane of saidshank, tip, and neck.

2. A pin having a straight shank bent aside and continued into a shorttip standing oblique to the axis of said shank and having a pointedextremity, the other end of the shank being bent into a short neckextending in a direction opposite to said tip, and a flattened head atthe outer end of said neck standing out of line with the axis of theshank but in a plane parallel therewith.

3. A pin having a straight shank bent aside on a curve and continuedinto a short straight tip standing oblique to the axis of said shank andhaving a pointed extremity, the other end of the shank being bent on acurve into a short neck extending in a direction opposite to said tip,and a flattened loop-shaped head at the outer end of said neck standingout of line with the axis of the shank but in a plane parallel therewithand transverse to the plane of said bends.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
